Data come from the GlobSci survey of authors of articles published in 2009 in four fields of science working in sixteen countries. Summary evidence suggests that migration plays an important role in the formation of international networks. Approximately 40 percent of the foreign-born researchers report having kept research links with colleagues in their country of origin. Non-mobile researchers are less likely to collaborate with someone outside their country than are either the foreign born or returnees. When the non-mobile collaborate, their networks span fewer countries. Econometric results are consistent with the hypothesis that internationally mobile researchers contribute significantly to extending the international scope and quality of the research network in destination countries at no detriment to the quality of the research performed. Results also suggest that the "foreign premium" on collaboration propensity is driven in large part by mobile researchers who either trained or worked outside the destination country where they were surveyed in 2011. With but one exception, the mobility findings persist when we estimate models separately for the US, Europe, and other countries. aHardcopy version available to institutional subscribers. aSystem requirements: Adobe [Acrobat] Reader required for PDF files. aMode of access: World Wide Web. 7aF22 - International Migration2Journal of Economic Literature class. 7aJ24 - Human Capital • Skills • Occupational Choice • Labor Productivity2Journal of Economic Literature class. 7aJ61 - Geographic Labor Mobility • Immigrant Workers2Journal of Economic Literature class. 7aO30 - General2Journal of Economic Literature class.1 aFranzoni, Chiara.1 aStephan, Paula.2 aNational Bureau of Economic Research. 0aWorking Paper Series (National Bureau of Economic Research)vno. w18613.4 uhttp://www.nber.org/papers/w1861341uhttp://dx.doi.org/10.3386/w18613
